Some people frequently use mouthwash to disinfect their mouths, thinking it helps with gum and tooth health. There are those who believe it is essential for eliminating bad breath when talking to someone. While using mouthwash correctly can be beneficial for preventing bacteria and tartar, improper use can disrupt the balance of bacteria in the mouth and lead to mold growth, so caution is needed.
Only Mouthwash Without Brushing?…Worsening Bad Breath
Mouthwash is a supplementary tool for brushing. After eating, one should brush to remove food debris and plaque, then finish with mouthwash. If food particles remain, the antibacterial effect diminishes. The reaction between food debris and the ingredients in mouthwash can worsen bad breath.
People with dry mouths may also experience worsened bad breath if they use mouthwash too frequently. If someone often has dry gums and mouth, it is recommended to choose alcohol-free products. Alcohol can dry out the mouth, exacerbating bad breath. Especially, using products designed for gum treatment too frequently can lead to changes in tooth color. Medical products should only be used after consulting a specialist.
Keep Mouthwash Short…“Frequent Use Raises Mold Concerns”
First, it is appropriate to rinse with mouthwash for about 30 seconds to 1 minute after brushing, waiting 20-30 minutes. If done too briefly, it will be ineffective, and if done too long, it can irritate the mucous membranes. Some people use mouthwash every 1-2 hours because they feel their mouth is dull. However, excessive use can eliminate beneficial bacteria and create an imbalance of bacteria in the mouth.
Dr. Park Chang-jin, a dentist and director of the Korean Society of Preventive Dentistry, warned on the YouTube channel ‘Knowledge Inside’ that "there is no need to use mouthwash daily," adding that "frequent use can kill the beneficial bacteria our body needs." He continued, "When beneficial bacteria die, bacteria and what is commonly referred to as 'mold' can proliferate in the mouth," mentioning that a typical example is the white mold known as 'candidiasis.'
Oral candidiasis is a white film that forms on the tongue, gums, and inside of the cheeks. When brushed, it peels off red and is painful. One may also feel a sting when eating soft foods or brushing. For those with dry mouths, gargling with salt water instead of products can be a good method.
